Horseshoe-calk.



MARTIN R. MYERS, OF GRAND RAPIDS, MICHIGANF HORSESHOE-CALK.

Specification of Letters Patent.

Patented A r. is, 1918.

Application filed April 19, 1917. Serial No. 163,197.

To all whom it may concern:

Be it known that I, MARTIN R. MYERS, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and useful Improvements in Horseshoe- Calks;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to horseshoes, and more particularly to horseshoecalks, and its principal object is to provide a calk member which isreadily applicable to any type of horseshoe, and which is so constructedthat lateral strain as well as longitudinal strain will be evenlydistributed upon a series of ,calk members when the same is attached tothe shoe.

Another object of my invention is to provide a calk which is so attachedto a horseshoe by means of bolts extending through the toe and heel lugsof the shoe that all shearing strain on the bolts will be entirelyeliminated, and wear and undue strain upon the component part of thecalks will be reduced to a minimum.

With these and other objects in view, which will appear from thedescription, my invention resides in the novel combination,construction, and arrangement of parts to be more fully hereinafterdescribed and claimed and taken in connection with the accompanyingdrawing forming a part of this application, and in which:

Figure 1 is a bottom plan view of a horseshoe constructed in accordancewith my invention;

Fig. 2 and Fig. 3 is a longitudinal sectional view on the line 3-3 ofFig. 1.

In the accompanying drawing, I have shown my improved calk as applied toan ordinary type of horseshoe H provided with a series of spacedscrew-receiving holes 1 to receive therein screws for fastening the shoeto the hoof of the horse, in place of the nails commonly employed.However, I desire it to be understood that my improved calk may beapplied to any type of shoe, and I have merely illustrated this form toshow one manner of applying my invention.

In detail my improved calk comprises a flat preferably forged steel bar2 which may is a side elevation of the same;

rolled, Stamped otherwise constructed, and Which is bent at its centralportion to provide a flat surface to engage a toe lug 3 of an ordinaryhorseshoe, and which is extended in divergent side portions 4 and 5 tothe rear of the shoe, and bent thereat adjacent the heel lugs 6 of theshoe and extended inwardly to form flanged portions 7 around the outerside and rear faces of the respective heel lugs. I desire toparticularly emphasize this construction and disposition of the calkmember, and. it will be seen that by this construction, the call; membercomprising the bar is extended externally of the heel lugs so asto-receive the outer side faces 8 and rear faces9 of the heel lugs inthe bend of the bar at this point which forms the flanges 7. Theseflanges are continued inwardly and terminate flush with the inner sidefaces of the adjacent heel lugs, and the lugs and flanges arerespectively apertured in alinement to receive bolt members 10therethrough for securing the calk member or bar to the shoe. By thisconstruction, it will be seen that any lateral strain on the calk memberwhich would tend to have a shearing effect upon the bolt is taken up bythe sides 4 and 5 of the calk .member against the outer side faces 8 ofthe lug, thereby eliminating any possible strain upon the bolt itself.

At the front or toe portion of the shoe, the middle bent ortion of thebar or calk member is formed to engage over the toe lug and also toengage the two side edges of the lug, as clearly illustrated in Figs. 1and 3, and the lug and bar are suitably provided with apertures toreceive therethrough connecting bolt members 11 similar to theconnecting bolt members 10 at the heel lugs and flanges.

When in applied position, the calk member will be extended and sodisposed on the under surface of the shoeas to form a threesided memberhaving the straight sides 4: and 5 extending from the toe lug to theheel lugs of the shoe and provided with the flattened central portionadjacent the toe lug as clearly illustrated in Fig. 1.

In the manufacture of the bar, it is beveled along its entire length onthe portion which is to form the inner side surfaces of the member, andthe bar is notched at spaced intervals to provide a series oflongitudinally alined integrally formed calks 12 through the entirelength of the bar except at the portion of the bar adjacent the toe lugsand the heel lugs respectively, as hereinbefore described. Gwing to thisconstruction, it will be seen that I have provided a calk member whichisconstructed of a series of longitudinally disposed alined calks whichwill prevent all lateral slipping of the shoe, and which is alsoprovided with call: members adjacent the toe and heel lugs of the'shoeto provide for a gripping action of the shoe and take up the longtudinalstrain thereupon.

While I have shownand described certain specific details and a certainspecific form in this embodiment of my invention, I desire it to beunderstood that I do not wish to limit myself to such, but that anychanges in the arrangement and detailsof construction may be made aswill fall within the scope of the appended claims.

I claim:

1. The combination with a horseshoe having toe and heel lugs, of athree-sided calk member adapted .to be vsecured thereon, one of thesides of said member engaging the outer fa'cevan'd side edges of the toelug, the

other two sides of said member having their rear ends bent inwardly toengage the rear iaces and outer side'edges of the heel lugs of the shoe,and means for fastening the calk g outer and rear faces of said heellugs, and

means extending through said lugs andcalk member for attaching the sameto said horseshoe.

In testimony I have hereunto set my hand in the presence of thesubscribing witnesses.
